And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 That they may enjoy the fruits of this (artistry): It was not their hands that made this: will they not then give thanks? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And the night is another Sign for them. We strip the day from it and they become plunged in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 We have created for them the like of it in which they ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 And they say: When will this threat come to pass, if you are truthful? 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 Then they cannot make bequest, nor can they return to their own folk. 50
